BACKGROUND

[0002] 1. Field of Invention

[0003] This invention relates to water craft protection.

[0004] 2. Description of Prior Art

[0005] Water craft owners are always trying to find new and improved ways to protect their investment from damage, whether induced by persons or nature and until now, used equipment designed for larger water craft. This current invention provides a higher level of protection for small water craft. “Bumpers” and “fenders” have been designed to attach to hand rails or cleats of large water craft by use of special knots. Owners of smaller water craft, such as personal water craft, have had inadequate protection.

[0006] In U.S. Pat. No. 6,161,494 Pontevolpe, et. al. describes a device to be permanently installed in a vessel or craft which is operated remotely and provides limited protection during mooring and docking operations. The current invention is designed to operate manually and provides protection over a larger area of the vessel or craft.

[0007] In U.S. Pat. No. 6,148,754 Sims, Jr. describes a device to be attached “onto the keel or hull of a watercraft” which is primarily under the water line of said vessel or craft. Sims' device is also designed as a permanent fixture to said craft or vessel. The current invention is designed to protect said vessel or craft, primarily, above the water line. The current invention is also a device to be attached only when desired by the operator of said vessel or craft.

[0008] In U.S. Pat. No. 6,021,729 DeRuscio describes a device consisting of molded PVC which attaches to the side of a personal watercraft in specific locations along the side of said craft. The current invention consists of an inflatable structure which encompasses the outward portion of said personal watercraft along the entire length of said personal watercraft providing an exceptionally higher level of protection and attaches more securely allowing better protection in situations that would be detrimental to said personal watercraft.

[0009] In U.S. Pat. No. 5,762,019 O'Rourke, et. al. describes a device “provided for protecting the top front portion of personal watercraft”. Said device is designed to protect the nose of the personal watercraft by utilizing protective layers of material. Said device does not provide protection for the lateral portion of said personal watercraft which the current invention does.

[0010] In U.S. Pat. No. 5,701,837 Harvey describes a device rectangular in shape which attaches to the gunwale and attaching to the side of a subject watercraft. Harvey's invention allows protection for a small area of said vessel leaving a large portion of said vessel unprotected. Harvey's invention, along with numerous others, are designed for larger vessels. The current invention is designed for smaller watercraft which do not have gunwales to attach said devices. The current invention provides a higher level of protection to said watercraft and attaches in a manner more suitable to said smaller watercraft.

[0011] In U.S. Pat. No. 5,671,692 Kimball describes a device which is constructed of plastic and is designed to attach to “boats” or docks or piers. Kimball's device is bulky and would take up a large amount of space while stored and provides a limited amount of protection only being in contact with a select section of said “boat”. The current invention is designed to utilize little space while deflated and stored and provide protection to the entire side of said watercraft, especially personal watercraft.

[0012] In U.S. Pat. No. 5,560,312 McPherson describes a device constructed of “closed cell foam cores with synthetic fabric covering”. McPherson also claims said device is “foldable for compact storage in the watercraft”. Said device also utilizes securing lines which require the user to attach them to the opposite side of said watercraft inhibiting the operation of said watercraft while said device is utilized. The current invention is constructed of a material suitable for inflation making it most bulky when inflated in its operational state and least bulky when not in use utilizing less storage space. In said operational state the current invention will provide a greater distance between said watercraft and any object would cause damage to said watercraft should they come in contact with one another. The current invention attaches along the horizontal edge of said watercraft keeping any securing devices from inhibiting operation of said watercraft while the current invention is in its operational state.

[0013] In U.S. Pat. No. 5,299,521 Loucks describes a device in a “sheet” form which is draped over the gunwale an hull of a watercraft. Louck's device provides protection for a small area of said watercraft. This device is not suitable for small watercraft which do not have a railing or suitable gunwale. The current invention attaches to said small watercraft which commonly do not have a railing or suitable gunwale. The current invention also provides protection to the entire length of said smaller watercraft.

[0014] In U.S. Pat. No. 4,584,958 Green describes a device “consisting of a plurality of one-piece bumper bodies” which are linked together to form a bumper system. This device is attached to a watercraft and draped over the edge between an area of exposed bulkhead of said watercraft and a docking station or other surface that would otherwise cause damage of some kind to said watercraft. Green's device is not affixed to be stationary and has the ability to move with the rolling of tide and wave common in the boating environment. The current invention is a inflated body which is securely attached to the outer most portion of said watercraft which is most likely to be damaged if not protected. The current invention provides protection to a greater area of said watercraft. The effectiveness of said current invention will not be changed with the movement of said watercraft as caused by before mentioned rolling of tide and wave common to the boating environment.

[0015] These previous inventions have failed to supply adequate protection for the smaller watercraft. These prior inventions do not contour to the outside of the water craft when applied. They do not stay in place as the craft begins to move and become more susceptible to damage. Previous inventions have only provided protection for specific portions of the watercraft. When higher levels of protection are most needed these prior inventions become less reliable. When not in use these prior inventions are difficult to store and often take up precious space and become hazards to the craft operator and passengers. The popularity of personal watercraft and other smaller types of crafts has grown after the creation of some of these prior inventions.

SUMMARY

DESCRIPTION Preferred Embodiment(s)

[0036]FIG. 4 is an overall view of my invention. The main body of the invention is an inflatable structure 12. The inflatable structure 12 is a tubular form with two end pieces 12 a and 12 b of like material. The end pieces 12 a and 12 b are shaped to give the invention its form. One, or body end pieces 12 a or 12 b are equipped with an air valve 20. Spaced out along the length of the body of the invention are securing loops 18. These loops are used to attach the securing strap 10 to the invention. On each end of the securing strap 10 are end hooks 14 a and 14 b. Along the strap 10, between the hooks 14 a and 14 b is a tension lock 16.

[0037] The main inflatable structure 12 is attached to end pieces 12 a and 12 b by use of hot air heat sealing machinery or suitable adhesive. The inflatable structure 12 also has a hot air, heat seal seam that runs the length of the structure. Along the outside of the inflatable structure 12 are securing loops 18 a thru 18 d. The securing loops 18 a thru 18 d are attached to the inflatable structure 12 by hot air, heat sealing or a suitable adhesive. The securing loops 18 a thru 18 d are used to attach the securing strap 10 to the inflatable structure 12. Secured to the ends of the securing strap 10 are end hooks 14 a and 14 b. Located between the end hooks 14 a and 14 b is a tension lock 16. The securing strap 10 runs thru the tension lock 16. Located in end piece 12 a and/or 12 b is an air valve 20 that is secured in place by use of hot air, heat seal machinery or a suitable adhesive.

Operation

[0038] The inflatable structure 12 is the main body of the invention. This portion of the invention, when fully inflated, is used to provide a safe buffer between the watercraft it is applied to and any object that may cause damage to it if they came in contact with one another.

[0039] The securing strap 10 is used to attach the invention to the water craft to be protected. The strap runs the length of the invention and attaches to the craft by use of end hooks 14 a and 14 b. In order to maintain tension between the end hooks 14 a and 14 b a tension lock 16 is used. The securing strap 10 is place thru the tension lock 16. When the strap 10 is pulled tight the tension lock 16 will maintain a secure hold on the securing strap. Air valve 20 is used to inflate and deflate the inflatable structure 12.

[0040] The invention may be in an inflated or deflated state when secured to a watercraft. First face the concave side of the inflatable structure, horizontally, toward the side of the watercraft. Place the end hook toward the front of the water craft thru the utility hole in the front of the craft. Attach the opposing end hook to the utility hole in the rear of the craft. Pull the loose end of the securing strap thru the tension lock until the strap is taut. Introduce air thru the air valve(s) until the inflatable structure is fully inflated. Be sure the concave portion of the inflatable structure is placed over the rub rail along the side of the watercraft. Adjust the tension of the securing strap as needed to keep taut and hold the invention in place on the watercraft.

Conclusion, Ramifications and Scope

[0041] The reader will see the current invention provides protection to the entire freeboard and gunwale of the watercraft while lightweight yet reliable and inexpensive. This invention can be operated by any person of almost any age. While the above description contains many specificities, these should not be seen as limitations of the scope of the invention, rather as an exemplification of one preferred embodiment.
